Biologie     Glossaire (ex. epibenthic)

A rare species (Ref. 4264) collected from muddy and sandy bottoms of estuaries and bays. Known to 'walk' over the bottom using its tentacular pelvic fins. Juveniles expatriate to tropical regions; adults mainly found in muddy estuaries where they pair. Sometimes they are seen partly buried but also feed during the day. Sometimes found floating on the surface (Ref. 48635). Sometimes occurs in seagrass areas (Ref 90102). Feeds on small benthic organisms (Ref. 68964).
